 Bemarks. — The Chemnitzian name of the above species, dis- 

 carded by Deshayes and Reed, should be restored.

Remarks. — The species described by M. Pldlippi as above, is 

 a distinct variety of caput serpentis. Although separated by Lis- 

 ter, it has escaped the notice of authors since. 



Compared with caput serpe^itis, it is smaller in size, not dilated 

 at the sides, darker in color throughout, and dorsal spots smaller. 

 The only description of the animal of caput serpentis, published, 

 so far as I can discover, is that in " Voy. d'Astrol," from which 

 caput anguis differs as follows : Mantle of a deep brown, shaded 

 with dark green, its tentacular processes red or red and white. 

 Siphon dusky, tentacles beyond the eyes light chestnut, base 

 white. Foot pale beneath and dusky above. The tentacular 

 fringe surrounding the end of the siphon is retractible. The 

 colors and their arrangement agree with the type, only darker.

Although considered by the late Mr. Cuming to be distinct, 

 I have classed it as a variety of C. jiavidus, Lam. It differs 

 only in the spire being flat or nearly so, occasionally slightly 

 concave, and its epidermis thicker and more rough. 



The following corrections should be made in the text of my 

 previous article. 



Page 117, 11 lines from bottom, read " lopas " for " Jopas." 

 " 120, 3 " " " " " it" for "otherspecies." 

 " 113, 10 " " " " " Lam " for " Linn." 

 " 112,21 " " " " "lives" for "lies."

 par " for " the last synonymy."
